Astroid is the new name of former logilab-astng library. It's an AST library,
used as the basis of Pylint and including Python 2.5 -> 3.3 compatible tree
representation, statical type inference and other features useful for advanced
Python code analysis, such as an API to provide extra information when
statistical inference can't overcome Python dynamic nature (see the
pylint-brain project for instance).

It has been renamed and hosted to bitbucket to make clear that this is not a
Logilab dedicated project but a community project that could benefit to any
people manipulating Python code (statistical analysis tools, IDE, browser, etc).
